"Air Masters designed a Mitsubishi mini-split system to replace a failed hot air system. The price of the system we wanted was pretty steep, but in line with other estimates. So we asked them if we could split the project into three phases: heat the main living area; add a zone for bed rooms; add a zone to heat garage (workshop) and guest room. They agreed and provided a reasonable estimate for the work, so we went with them. First phase was great. Work was done promptly and the system worked well. Second phase also went off reasonably well, although the craftsmanship on the install wasn't up to standard and there were some communication issues with the required surge suppressor. But in the end it all worked out. When the time came to do the third phase, everything fell apart. When the estimator came out to plan the work and give us the price we were told that the plan would not work because the outside unit did not have the capacity to support the inside unit for the third phase - even though nothing had changed in the plan. The same rooms were being heated - but now the system that they designed for precisely this application would not work. I think the problem may have been that Air Masters did not really understand the equipment that they were installing and the project manager had quoted and/or ordered the wrong outside unit. I can understand that. What I can't understand is their failure to stand behind their work or really to even look for a solution. The estimator who came out stopped responding to calls and the company owner did not respond to e-mails or phone calls. So in the end it was not even possible to discuss options with them. We are now in the market for a mini-split system for a rental property and Air Masters will not be on the list of contractors that we call for estimates."

"Best price for unit and installation of the companies I looked into, but customer service left something to be desired. Took a very long time to get someone out to install the new filter set up at the air intake, with poor communication on their part. That part of the job was done poorly and had to be redone at my insistence. Also had the red warning light come on. Called about that and no follow through. Again. Really wanted to like these guys, but unimpressed with the experience."

Air Conditioning FAQs, answered by experts

Yes, a dirty air filter can cause a higher electric bill. That’s because clogged filters make it harder for air to flow through your HVAC system, which forces it to work harder and use more energy. According to the U.S. Department of Energy, replacing dirty filters can save you between 5% and 15% in utility costs.

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

The cost to install a ductless mini-split AC system ranges from $2,000 to $14,000, depending on the type of unit, the number of zones or rooms, and the complexity of the installation. On the low end, a system for one or two zones in a single room costs around $2,000. Covering two zones for more rooms can cost between $6,000 and $8,000. For a larger multi-zone system to cover an entire home, costs can be $14,000. If you don’t already have an AC system in place, you may need to add the cost of permits, an electrician, and a concrete pad.

It is normal for the attic to be hotter than the rest of the house in the summer, but only by about 10 or 20 degrees. Attics that aren’t properly insulated or ventilated can reach temperatures of 130 degrees or more which can cause damage to the home’s structure, including the roof, wood framing, and HVAC system.

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.
